My invention relates to forging machines, and more particularly to'forging machines adapted especially for use in ysharpening and forming drill bits.

During the forging of heated articles, it is desirable thatfmeans be provided for cooling the portions of the forging machine supporting and holding the-article in place so that these portions will not be softened by the heat to a point where they will be deformed lby the forging action. It is also desirable that portions ofthe heated article be cooled before the forging action `takes place so as to stiien up the metal in these portions and confine the forming of the metal to the portions of the article to be shaped. In order that the desired cooling effects may be obtained, I have provided in the forging machine of my invention improvedA means for delivering':raf` cool',l ing fluid to parts to be cooled, and, `in order that the delivery of cooling fluid and the operation of the forging machinemay take place :at the proper time, I have provided improved means for controlling the flow of cooling fluid and the flow of operating fluid to the hammerpiston of the machine. To increase the efficiency of my forging machine I have also provided improved means for releasing the article from its supporting means and ejecting the article from its supported position after the forging opera-tion has lbeen completed.

An object of my invention is to provide an irnproved forging machine. Another object of my invention is to provide a forging machine having improved means for cooling the parts of themachine supporting a heated article to be forged. Still another object of my invention is to pro-` vide an improved forging machine having improved means for controlling the supply of a cooling fluid and the flow of operating'uid to the machine. Yet another object of my invention is to' provide a forging machine having a forging hammer which is movable to operating and nonoperating positions, and having improved means for moving the hammer to such positions. -Still another object of my invention is to provide an improved forging machine having control means including a single operating member for adjustingthe position of theforging hammer, controlling the flow of operating fluid to the machine, andV controlling the ow of a cooling fluid to the supporting means for the article to be forged. Another object of my invention is to'provide a forging machine having improved means for releasing the forged` article from its supporting means and ejecting the article from its supported position. Yet another object-of my invention'is to provide an improved forging machine having an adjustable hammer motor vand means forad-l justing the same to facilitate the insertionand removal of an article to be forged, also having Fig. 3 is anenlarged vertical sectional f'View taken on theplane ofthe line '3-3'of'Fig. l.-

In'the illustrative embodiment of my invention there is shown'a-forgingfmachine, agenerally designated I, having Aa hollowloase framef2 on the -topof which-a platform 3 is connected, as by boltsy '4, andv-sli'dably'mounted on the'platform 3-is a `standard for a'forging hammer, Agenerally designated V'6. The platform 3 is prof vided with guideways 8 receivingt guide portions S'4 on thefstandard for guiding themovements of the forgingV hammerV over the platform. Formed on the lower `side` of the standard is a rack leprojectingf'in-to a recess vil in the platform and engageable atits ends with surfaces l2 and I4 on the platform for limitingmove- 'ment of the forging hammer into its operating and non-operating positions, respectively. Projecting through an opening I6 in the platform is a gear segment I1 meshing with the rack i8, and the gear segment is fixed to a shaft I8 eX- tending transversely of the base frame 2 and rotata-bly supported at its ends in the side walls of the frame. At one end of the shaft I8, as shown in Figs. 8 to 10, is an arm 20 having a hub portion 2| fixed to the shaft, as by a key 22. Pivotally mounted on the shaft I8 is an operating lever 24 which extends, as shown in Fig. 9, between flanges 25 and 23 formed on the arm 20, and a spring. 28 acting between the flange 2S and the operating lever tends to hold the arm and the lever in spaced angular positions relative to each other. As the lever 24 is swung upwardly it acts against the flange 25 and swings the arm 20 which, in turn, rotates the shaft I8 in a counter-clockwise direction, as viewed in Fig. 8. The gear segment I1 rotates with the shaft I8 and moves the standard rearwardly on the platform 3. When the lever is swung downwardly toward its horizontal position, as shown in Fig. 8, it acts through the spring 28 to swing the arm 28 and rotate the shaft I8 in a direction to move the forging hammer toward its operating position. After the hammer has been moved to its operating position and the front end of the rack I8 engages the surface I2 resisting further forward movement, the lever 24 may be swung a short distance relative to the arm 20 against the force of the spring 28.

Fitting within an opening 39 in the platform 3 and resting on a thickened wall portion 3i oi the base frame 2 is a die block 32 having an opening 33 within which the article to be forged, in this case a drill bit 34, is received. Extending through an opening 38 in the wall portion 3I into the opening 33 in the die block is an elongated support member or holder 31 having a threaded end portion 38 to which the drill bit 34 is adapted to be connected. Formed on theholder member 31 adjacent the portion 38 is an annular flange 33 engageable with a wear bushing 40 which supports the member during forging. The portion of the member 31 below the flange 39, shown herein as being of hexagonal shape, projects through the opening 35 into the open center of the frame 2,

the opening 36 being of sufficient size to permit free rotation of the member therein. Connected to the lower side of the wall portion 3l is a frame 42 supporting a ratchet mechanism, generally designated 43, operatively engaging the member' This ratchet mechanism comprises a pawl carrier 45 which is rotatably supported in bearings 41 and 48 carried by the wall portion 3l and the 'frame 42, respectively, and extending through lsuch that the pawl carrier is rotated with the ratchet 50 when the latter rotates in a clockwise direction, as viewed in Fig. 5, but remains stationary with the pawls sliding over the teeth when the ratchet rotates in the opposite direction. It will be noted that the direction of rotation of the pawl carrier by the ratchet is such as to effect at least partial release or loosening of the threaded connection between member 31 and the drill bit.

In order to eifect a rotation of the ratchet there is provided on the latter gear teeth with which a gear segment 5B meshes. The gear segment 56 is pivotally mounted, as shown in Fig. 4, on a pin 58 bolted to the side of the base 2, and an operating lever 59 formed integral with the gear segment, extends through an opening 60 in the base 2 and is provided with a foot pedal 6I adapted to lbe actuated by the operator. A spring 62 connected to the base 2 and the lever 59 normally holds the latter in such a position that the gear segment 55 may be operated to actuate the ratchet mechanism. At times the forged drill bit may be so tightly connected to the member 31 that additional means are needed to loosen it. To take care of these conditions I have provided a cylinder 64 connected, as shown in Fig. 5, to an inside wall of the base 2 and containing a reciprocable piston 65 having a piston rod S6 which is pivotally connected by a link 61 to the gear segment 56. A iluid supply connection 69 opens into the cylinder 54 at the outer end of the latter.

In order that the lower portion of the drill bit and the threaded portion of the member 31 may be cooled, I have provided a bore 1I extending from the lower end of the member 31 longitudinally through the latter into the threaded portion 38. Arranged below the lower end of the member 31 and connected to the side of the base frame 2, as `by bolts 12, is a trough-like member 13 having a -drain connection 14. Extending upwardly within the trough of the member 13 is a pipe section 15 which passes through the bore 1I to a point adjacent the threaded portion 38 of the member 31. The pipe section 15 is somewhat smaller than the bore 1I in diameter so as to provide a space between it and the walls of the bore through which cooling liquid may escape to the trough of the member 13. The lower end of the pipe section 16 is connected in communication with a passage 11 in the member 13, and a fluid supply connection 19 is arranged to deliver uid to this passage.

To effect an ejection of the forged drill bit from the die block I have provided a bell crank lever 8l which is pivotally supported by a shaft 32 extending transversely of the base frame 2. The lever has an arm 83 engageable with the lower end of the member 31 and an arm 84 carrying at its outer end a roller 85. Attached to the shaft I8, as by a key 83, is a cam member B1 having a portion 8B which is engageable with the roller 85 when the shaft I8 is rotated to position the standard 5 at the rearward end of the platform 3, When the cam portion 89 engages thc roller 85, the bell crank lever 8i swings about the shaft 32, lifts the member 31 and ejects the drill bit from the die block 32. The cam member has another cam portion 98 engageable by the roller 85 for holding the bell crank lever in a position which permits the member 31 to drop through the opening 36 until it is supported by the wall portion 3 i.

The forging hammer 8 may be of any type desired but, for purposes of illustration, I have shown a forging hammer of the piston hammer type, such as is shown in Patent 1,440,807, issued to me on Jan. 2, 1923, the same comprising a cylinder 92 having a piston 93 reciprocable therein and adapted to deliver its blow through a striking bar 94.

As a result of my invention it will be noted that there is provided an improved forging machine in Which portions of the supporting means for the article to be forged, as Well .as portions of the article itself, are cooled before any forging action takes place. The forging hammer is movable toward operating and non-operating positions, and, on movement toward its non-operating position, the forged article is automatically ejected from the die. A control means including a single operating member controls the positioning of the hammer, the flow of cooling fluid, the flow of operating fluid for the hammer, and the ejecting of the forged article from the die. Because of the control means provided there is assured an operation of the machine to perform its different functions at the proper time, and the eiiiciency of the machine is increased.

While I have in this application specifically described one form which the invention may assume in practice, it will be understood that this form of the same is shown for purposes of illustration, and that the invention may be modified and em- -bodied in various other forms Without departing from its spirit or the scope of the appended claims.
